Hi guys looking for advice for my project ??
I have a sectional garage roof 10ft x 18ft i currently use it as my gym at the moment been fine upto this winter which has caused a fair bit of damage a few holes and cracks etc. I am covering the roof with 18ft box profile roofing sheets and finishing with angled cladding allround. my question is this i have installed 4x2 supports onto metal purlins inside the garage for support and fixing my roof to. I have then above the roof on top side installed 2x2 to hold the new roof in place. will i need to install somekind of insulation between the box profile and cement sheets or is this best left as an air gap. Will the old cement roof act as a vapour barrier too and prevent any condensation.
Thanks
